Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a size liquid drench device for a warping sizer, and particularly to a means for reliably preventing clogging of a size liquid drench supply hole.

Technical background of the invention During the gluing process, it is necessary to temporarily stop the operation of the warping sizer in order to deal with thread breakage, etc. During operation, a moderate amount of size liquid adheres to the surface of multiple rolls, but when operation is stopped, the size liquid on the surface of the rollers becomes dry or half-dry, so when operation resumes, the thread may have uneven size. or fuzz may appear.

Such a dry or half-dry state of the glue can be solved by constantly dripping (drench) the glue liquid onto the surface of the roller during the downtime of the operation. The dropping of the size liquid must be stopped at an appropriate time after restarting operation to prevent excessive supply of the size liquid. However, when the dripping of the glue solution was stopped, the glue adhered to the supply hole of the drench drain.
Due to a decrease in the viscosity or temperature of the size liquid, the supply hole is blocked, and the size liquid cannot be dripped smoothly in the next drenching operation.

Prior Art Therefore, for example, the invention of Utility Model Application Publication No. 51-72539 was
A steam outlet is formed near the glue dripping chamber,
A technique for heating the size liquid in the size liquid dripping chamber is shown. In this technique, since the size liquid is heated to an appropriate temperature, clogging due to coagulation of the size liquid can be prevented at least in the drip hole portion. However, since glue has a certain degree of viscosity,
Even in a heated state, if it comes into contact with air temporarily, it will stay in the drip hole. Therefore, the above technique cannot reliably and actively prevent clogging of the drip hole.

Purpose of the Invention Therefore, the purpose of the present invention is to proactively prevent clogging of the size liquid supply hole and to enable uniform supply of size liquid to be carried out smoothly and reliably.

Summary of the invention Therefore, the present invention places a clogging prevention nozzle on the outside or inside of the drench tube for dripping the size liquid, and when the size liquid has finished dropping, the nozzle is directed toward the supply hole of the drench tube. Fluid is injected from the nozzle, thereby forcibly discharging the remaining glue inside the drench tube, and actively preventing clogging of the supply hole at the lower end of the drench tube.

Configuration of the Embodiment The configuration of an embodiment of the present invention is shown in FIG.

That is, FIG. 1 shows the sizing liquid drenching device 2 of the present invention in relation to the sizing section 1 of a warping sizer. Gluing part 1 of warping sizer
Immersion roll 3, sizing roll 4
and a squeeze roll 5. The immersion roll 3 and sizing roll 4 are
The lower surface portion contacts the size liquid 7 housed inside the size box 6 and is supported in a rotatable state. The thread 8 is wound around the immersion roll 3 and the sizing roll 4 in an S-shape while being guided by a plurality of guide rolls 9, and runs in the direction of the arrow. On the other hand, the squeeze roll 5 is disposed above the sizing roll 4, in contact with it, and rotatably provided in a non-contact state with the size liquid 7. Further, the size liquid 7 overcomes the overflow weir 10 inside the size box 6 and is stored inside the cavity box 11. The size box 6 and the cavity box 11 are connected by a circulation pipe 12,
The water is circulated by a pump 13 interposed in the middle. Note that the circulation amount of the size liquid 7 can be adjusted by a flow rate control valve 14 interposed in the circulation pipe 12.

Now, the size liquid drenching device 2 of the present invention is equipped with a drench groove 15 and a nozzle 16 for preventing clogging as main parts. This drench groove 15 is provided along the longitudinal direction of the squeeze roll 5 at a slightly eccentric position above the squeeze roll 5, and is, for example, of an open top type, with a plurality of continuous or discontinuous supply holes 17 integrally formed in the lower end portion. is forming. Further, the outlet side of the pump 13 has a control valve 18 and a flow rate adjustment valve 19 interposed therebetween.
It is branched by a supply pipe 20 and connected to a position slightly above the drench groove 15. Further, the nozzle 16 for preventing clogging is provided above the drench groove 15 in the longitudinal direction, and is connected to a pressure fluid source 23 through a pipe 21 with a control valve 22 interposed therebetween. This source of pressurized fluid 23 is ready to deliver a fluid 24 at a suitable pressure, such as air or steam at a suitable pressure, to the nozzle 16 via a control valve 22 .

The control valves 18 and 22 are both controlled by a control device 25. This control device 25 is equipped with a program cam or a program timer, and controls the control valves 18 and 22 in relation to the operating state of the gluing section 1 of the warping sizer.
Performs sequence control for opening and closing.

Function of the Embodiment Next, the function of the size liquid drenching device 2 of the present invention will be explained with reference to FIG. 2 in relation to the pasting section 1 of the warping sizer.

Figure 2 shows a stop period A, a low speed operation period B, and a high speed operation period C of the gluing section 1 of the warping sizer.
In relation to this, the open and closed states of the control valves 18 and 22 are shown. During the stop period A, the control valve 22 is closed and the control valve 18 is set to the open state. Therefore, the size liquid 7 is supplied to the inside of the drench groove 15 via the supply pipe 20. The size liquid 7 inside the drench groove 15 flows out from the supply hole 17 and adheres to the surfaces of the squeeze roll 5 and the sizing roll 4 while flowing down. Therefore, the size liquid 7 on the surfaces of the squeeze roll 5 and the sizing roll 4 will not become dry or half-dry regardless of whether they are stopped.

Since the control valve 18 immediately closes during the subsequent low-speed operation period B, the size liquid 7 is no longer supplied to the drench drain 15. After that, the control valve 22 remains closed only for the time T1. During this period,
Size liquid 7 remaining inside the drench drain 15
It is set to discharge all. After this time T1 has elapsed, the control valve 22 is activated for an appropriate time T1.
2 is in the open state, so the fluid 24 is injected from the nozzle 16 for clogging prevention toward the inside of the drench groove 15. At this time, the fluid 24 in the jetting state blows off the size liquid 7 adhering to the supply hole 17 with a jet flow, thereby opening the supply hole 17. After this time T2 has elapsed, the high speed operation period C begins with the control valves 18 and 22 remaining open. Since the supply hole 17 is forcibly cleaned in this way, the subsequent stop period C
The size liquid 7 can be supplied without any problem.

Modified example of the invention In the above embodiment, the drench groove 15 is of an open top type, but this drench groove 15
may be configured as a closed type as shown in FIG. 3, and the nozzle 16 may be connected to the inside thereof. Further, the fluid 24 may be air, steam, or water at an appropriate temperature. However, when this water enters the inside of the size box 6, the concentration of the size liquid 7 changes. Such inconvenience can be prevented by supporting the drench gutter 15 in a movable state and retracting it to a position away from the upper surface of the size box 6 during cleaning. In this case, the supply pipe 20 and the pipe 21 must be connected by a bendable pipe.

Effects of the invention In this invention, an appropriate amount of sizing liquid is forcibly supplied to the surfaces of the squeeze roll and sizing roll during the period when the sizing section of the warping sizer is stopped, so that the sizing liquid on the surfaces of those rolls does not dry or dry. Also, after the size liquid is dripped through the supply hole of the drench tube, the nozzle sprays fluid at an appropriate pressure toward the supply hole, cleaning the supply hole and reliably preventing clogging. The subsequent dripping operation of the paste liquid is carried out smoothly.
